How To Remove A Badly Corroded Car Battery, Replace With New

My battery terminals were really corroded. It was so bad that the bolts and nuts could not be saved. When I got a new set of bolts and nuts, even though they were purchased based on the year and make, they didn’t fit well. I will show you how to fix that.

4. what about enclosures?
